What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Right main laning gear attach fittings failed on landing roll. (.4)the Fokker F100 was on landing rollout when the right main landing gear collapsed. Review of company maintenance records revealed the torque link damper on the right main landing gear was serviced using a company maintenance task/job card. The procedures did not follow the maintenance procedures listed in the aircraft manufacturer's maintenance manual, and the required tools (replenishing gun) was not available to service the torque link damper assembly. Examination of the failed components by the NTSB materials laboratory division revealed fractures from the main fitting had a chevron pattern caused by overstress originated at the base of the upper torque link attach lug. No preexisting cracks were noted.
